Please suggest a good CPU water cooler

I got the H100i with 4 SP120 Quiet Edition fans.

I've found the arrows on the fans. What's the point of the arrow that's pointing to the side? You said there is "one arrow pointing around the fan to show the direction of rotation" but why do I need to know that?

So I'm going to have my radiator on the top of my case with 4 fans attached to the radiator (2 on each side). It only comes with 8 screws to fit the fans the radiator, where do I get another 8 screws from?

Also how do I attach the radiator to the top of my case as there are no screw holes left on the radiator as those are occupied by the screws attaching the fans to the radiator.

Remove those screws holding on the fans and put them through the case, then the fans on the underside and finally screw into the radiator. Those fan screws do all the work of holding it on the case. As for the direction of rotation, it allows you to work out the airflow direction. No point in having the fans working against each other :-P

So for the rotation should the fans all have the arrow side facing in the same direction?

Why does the rotation angle matter? I thought it's just the airflow direction that matters and that's what decides if it's push/pull?
